Imagine one day, a certain tech giant really develops a Quantum Computer that can instantly crack RSA Secret Keys, and hackers get their hands on it. What will happen then?

The account security of traditional banking systems could collapse directly. SWIFT cross-border transfers may be intercepted, credit card data could be compromised, and the entire fiat currency system will undergo an unprecedented credit shock. Wall Street may come to a standstill due to a technological panic.

But what about blockchain? This is where it gets interesting.

Stablecoins like USDD that operate on high-performance public chains such as Tron have inherently stronger anti-quantum resilience due to their underlying hash algorithms (such as SHA-256). More importantly — smart contracts can be upgraded. Once a threat truly approaches, DAO governance can rapidly initiate proposals to migrate the core contracts to anti-quantum signature algorithms. This kind of code flexibility is something that bank systems still clinging to decades-old COBOL cannot compare with.

With the transparent over-collateralization mechanism and price stability module, the value of this type of stablecoin is guaranteed by mathematical consistency rather than the security of a bank's database. Once quantum panic occurs, funds will instinctively flow towards these assets that are "mathematically certain."

In simple terms, when traditional finance is paralyzed by technological panic, the agility of blockchain has become the biggest moat.
